Ohio EPA’s Division of Drinking and Ground Waters “participates in many activities to ensure Ohio’s tap water is safe to drink and our precious water resources are protected for future generations.” DDAGW ensures compliance with the federal Safe Drinking Water Act and regulates and monitors Ohio’s more than 4,800 public drinking water systems. Ohio Administrative Code (OAC) rules administered by DDAGW can be found here. Ohio Department of Health has established drinking water standards for private water systems based on the federal drinking water standards for public water systems.  


House Bill No. 512

Passed 5/25/16, went into effect 9/9/2016

This Act amended the Revised Code to establish requirements governing lead and copper testing for community and nontransient noncommunity water systems, revised the law governing lead contamination from plumbing fixtures, and revised the laws governing the Water Pollutions Control Loan Fund, Drinking Water Assistances Fund, and the Ohio Water Development Authority. It ensures stricter compliance with the federal LCR. The amended code requires public water systems to conduct sampling for lead and copper and establish a schedule for sampling that considers the age of the water system, whether the public water system is complying with corrosion control requirements, and other risk factors. HB 512 re-defines the term “lead free” by significantly reducing the amount of lead from 8% to a weighted average of 0.25% lead. 


Control of lead and copper – lead service line requirements (Ohio Administrative Code, Rule 3745-81-84)


Ohio’s Lead and Copper Rule was revised to require specific work practices when performing field work that could disturb LSLs, starting on October 1, 2018. The water system must notify customers of the work performed at least 45 days in advance and explain the risks involved (including the potential for higher levels of lead in water). “The water system shall identify the initial number of lead service lines in its distribution system… The water system shall replace annually at least seven per cent of the initial number of lead service lines in its distribution system.” Water systems are only required to replace the part of the lead service line that they own. They may offer to replace the portion owned by customer but do not have to cover the cost of replacement. Testing of partial LSL replacements will take place and the results reported to owners/customers. A “water system shall offer and provide drinking water treatment unit filters up to a period of three months to consumers in the area impacted by the replacement.”
